Definitions

  • the invention relates to a lamp having an attached cable, in particular for installation in a reflector housing for the lighting and marking of aircraft taxiways.
  • halogen incandescent lamps are preferably employed in this situation, the light from which is focused by means of a reflector and radiated directionally. It is however also conceivable to employ high-pressure discharge lamps. For the sake of simplicity, halogen incandescent lamps with a spiral-wound filament are assumed in the following, whereby high-pressure discharge lamps with an electric arc should however also be included.
  • a precise positioning of the light source, in other words of the filament or the arc, within the reflector environment is necessary for focusing the light.
  • Production tolerances in the manufacture of the lamp glass envelope would require a complex readjustment following installation of the lamp in order to achieve precise positioning at the focal point of the reflector environment.
  • the base of each individual lamp glass envelope is actually adjusted to the eventual focus position in the reflector during the assembly of the lamp. In the case of a defective lamp, the entire module comprising glass envelope and base is replaced and no readjustment is needed.
  • One object of the present invention is to provide an improved lamp of the type described and a corresponding manufacturing method.
  • One aspect of the invention is directed to a lamp which has a lamp glass envelope having contact pins projecting from its end and which is held in a socket receptacle having an insulator.
  • the insulator holds a small metallic tube between a contact pin of the lamp envelope and a current-feeding connecting cable in at least one through hole, with which small tube the contact pin is crimped and the connecting cable is connected.
  • Another aspect of the invention is directed to a method for manufacturing a lamp, wherein a lamp glass envelope having contact pins projecting from its end is held in a socket receptacle having an insulator, and wherein at least one contact pin is crimped to a metallic small tube, which small tube is connected with a current-feeding connecting cable and is held in a through hole in the insulator.
  • lamps having an attached cable can be manufactured particularly easily and reliably by crimping in the base.
  • crimped connections can be implemented without heating and checking melting metals, and thus more simply and cost-effectively.
  • the at least one small metal tube is crimped on the glass envelope side to the corresponding contact pin and connected on the opposite side to a current-feeding cable.
  • the cable can for example be welded, soldered or, particularly advantageously, likewise crimped to the small tube.
  • small tube is to be understood as follows from this context: It does not necessarily need to be a small tube completely closed in the circumferential direction. A remaining slot would not have a detrimental effect as long as the contact pin can be inserted and retained. It can also be sufficient to provide a cross-sectional profile of the small tube suitable for inserting and retaining the contact pin only in some places along its axial length. In this situation, a simple small tube having a circular ring cross-section remaining the same over the axial length is particularly preferred.
  • the socket receptacle with the lamp glass envelope can, as known, preferably be secured in a reflector by means of a position adjustment flange.
  • the flange is preferably mounted in a metal sleeve, whereby the position of the flange is related to the ideal location inside the reflector of the spiral-wound filament generating the light.
  • At least one of the contact pins must be electrically insulated, in particular with respect to a socket receptacle having metal parts, as mentioned above for instance.
  • the other contact pin could also be connected to the metal sleeve or other conducting surrounding parts.
  • the insulator can for example consist of a small glass or ceramic tube.
  • the insulator is a ceramic cuboid having a through hole for receiving the contact pin and the small metal tube. More preferably, two holes exist in the ceramic cuboid for the two contact pins, such that the two contact pins are insulated from one another and from their surroundings.
  • connection of the connecting cable or cables to the small metal tube or tubes provision can be made for a broadening of small tube and/or cable, such that the small tube can no longer be withdrawn from the insulator towards the lamp glass envelope. A safeguard against accidentally pulling the lamp glass envelope out of the socket receptacle can thus be achieved. A crimping also of the connecting cables in the small metal tube can preferably also be considered here.
  • the metal sleeve preferably abuts against the flat end by means of metal lugs bent inwards.
  • the metal lugs may also snap into notches or behind grooves in or on the flat end and additionally fix the lamp glass envelope in the socket receptacle. From this, a particularly effective safeguard against an accidental disconnection then results. In any case, the lugs touching the pinching serve to better dissipate the heat generated in the lamp.
  • the metal sleeve has apertures for improved heat dissipation in the region of the insulator. These apertures are advantageously placed on the broader sides of the flat glass pinching.
  • the aforementioned lugs protruding into the interior of the metal sleeve can be implemented particularly simply by means of cuts in the sheet metal of the metal sleeve.
  • Additional apertures in the region of the lugs result in an unconstrained manner if the cuts defining the lugs are larger than the lugs themselves and encompass a contiguous area.
  • the cuts can be made for example by using punching or cutting tools.
  • the insulator receiving the small metallic tubes can be constructed in two parts. For example, a first part can receive the small tubes and a second part can contain holes through which the connecting cables are fed to the small tubes. This facilitates the assembly or the connection of connecting cables and small tube and makes it possible to remove the insulation from the current-feeding cable over an extended length, for example in order to avoid damage caused by heat to the insulating coating of the cables.
  • the crimping of contact pin and small metal tube can also be performed even if the small tubes are already mounted in the socket receptacle.
  • side recesses are located in the insulator in the region of the ends of the small tubes on the glass envelope side, which side recesses in conjunction with the apertures in the metal sleeve enable access for crimping after insertion of the contact pins.
  • the step of crimping small tube and contact pin can also take place prior to assembly.
  • the following sequence can advantageously be observed when assembling the lamp: Firstly, the small metal tubes (or tube) are (is) inserted into the through hole in the first insulator part on the glass envelope side, then the connecting cables (or cable) are (is) crimped to the small tubes (or tube), whereby the cable-side small tube ends are deformed such that the small tubes are prevented from being pulled out on the glass envelope side. Subsequently, the second insulator part is pulled over the connecting cable or cables, with the result that the freestanding cable-side small tube ends are enclosed by the insulator.
  • FIG. 1 shows a first insulator part having two small metallic tubes held therein.
  • FIG. 2 shows the ensemble from FIG. 1 having connecting cables connected to the small tubes.
  • FIG. 3 shows the module from FIG. 2 having a second insulator part.
  • FIG. 4 shows, based on FIG. 3 , the encasement of the insulator by the metal sleeve.
  • FIG. 4 a shows cross-sections of the metal sleeve from FIG. 4 .
  • FIG. 5 shows the module from FIG. 4 , whereby the metal sleeve also holds a lamp glass envelope.
  • FIG. 6 shows the module from FIG. 5 , to which a positioning flange has been added.
  • FIGS. 1 - 6 in this order consequently illustrate the progress of a preferred manufacturing method and show a lamp according to an embodiment of the invention in FIG. 6 .
  • FIG. 1 shows two small metal tubes 1 which are held in a first insulator part 2 made of ceramic.
  • this first insulator part 2 has recesses 3 in the material which in a later method step permit access for the crimping of the small tubes 1 .
  • the small tubes 1 At their end on the glass envelope side the small tubes 1 have a broadening 20 which safeguards the small tubes against pulling out or falling out on the cable side from the first insulator part.
  • the extension of the first insulator part in the direction of the small tube axis is dimensioned such in this situation that a part of the small tubes sufficient for the crimping to the cables protrudes out of the insulator part if the broadening 20 of the small tubes terminates flush with the corresponding surface of the first insulator part.
  • FIG. 2 shows the connection of two connecting cables 4 to the small tubes 1 .
  • the cables 4 are stripped of their insulation and crimped to the small tubes.
  • the crimping 5 pinches the small tubes in such a way that it is no longer possible to pull out the small tubes from the first insulator part on the lamp glass envelope side (not shown).
  • the small tubes are advantageously already held by the first insulator part, which simplifies the crimping to the cable ends.
  • FIG. 3 shows a second insulator part 6 which attaches directly to the first insulator part 2 and completely surrounds the crimping of small tubes 1 and connecting cables 4 . Also illustrated are cable shoes 7 which serve by way of example for connecting the cable ends to a power supply.
  • a metal sleeve 9 surrounds the module comprising first insulator part, second insulator part and small metal tube.
  • This module is fixed in the metal sleeve by means of a punctiform indentation 10 of the metal sleeve and sheet metal edges 11 bent over inwards.
  • the metal sleeve On its wide sides the metal sleeve has metal lugs 8 which later touch the glass pinching to provide heat dissipation and can where applicable also fix said pinching by snapping into corresponding depressions and grooves in the metal sleeve 9 .
  • the metal lug 21 on a narrow side of the metal sleeve follows the same principle.
  • the metal lugs 8 , 21 pressed against the lamp glass envelope are likewise used for improved heat dissipation. This is particularly useful on account of the fact that the high temperatures of the lamp glass envelope occurring during operation of the lamp have disadvantageous effects on the tightness of the glass seal in the region of the current-conducting contact pins and shorten the service life of the lamp which can be achieved in principle. This problem is regarded as the cause of the loss of tightness resulting from oxidation of the molybdenum foils used as current lead-through.
  • FIG. 4 a illustrates the implementation of the lugs 8 , 21 by means of sectional representations of the metal sleeve.
  • the punctiform indentations 10 and the sheet metal edges 11 for fixing the insulator are also represented.
  • apertures 12 In the region of the insulator and the lugs 8 bent inwards are situated apertures 12 for the purpose of improved heat dissipation. Apertures and lugs are defined by cuts 13 into the metal sleeve.
  • FIG. 5 shows a lamp glass envelope 14 in the state in which it is built into the metal sleeve.
  • the lamp glass envelope 14 has a wedge-base lamp socket 15 , which the lugs of the metal sleeve touch as described above by pressing against it.
  • the contact pins 16 of the lamp glass envelope 14 mate into the small metal tubes and are crimped to said small metal tubes at the points 17 . Since the small tubes cannot be withdrawn on the glass envelope side by reason of the pinching of the cable-side ends associated with the crimping of the cable, the crimping 17 increases the strength of the bond of glass envelope 14 and metal sleeve and safeguards the former (additionally) against being accidentally pulled out.
  • FIG. 6 shows the basic arrangement of a position adjustment flange 18 on the metal sleeve.
  • the position adjustment flange has projections 19 which are spot welded to the metal sleeve.
